Square D | ME36600LS | Circuit Breaker | 600A | 3-Pole | 600V | 65kA

Square D ME36600LS is a rugged, 600A, 3-pole circuit breaker designed for demanding three-phase power systems. Rated for up to 600V with a 65kA interrupting capacity, this unit is built to protect equipment and keep downtime to a minimum in industrial environments. It’s the right choice for maintenance, retrofit, and replacement projects where exact specifications matter.

Key Specifications

• Amperage: 600 A
• Poles: 3-pole
• Voltage: 600 V
• Interrupting Rating: 65 kA

Why this breaker matters

Industrial power distribution demands reliable protection that can handle high fault currents. The ME36600LS delivers precise overcurrent protection for 3‑phase circuits, enabling safe shutdown and helping prevent damage to panels, wiring, and connected equipment. Its 65kA interrupting rating provides a robust margin for fault scenarios typical in manufacturing floors, data centers, and large mechanical systems.

Ideal use cases

• Maintenance and planned replacement of aging or obsolete breakers in commercial/industrial panels
• Retrofits where a direct, exact-specification switchboard option is needed to maintain panel consistency
• Spare provisioning for facilities standardized on Square D ME-series breakers to reduce downtime during service calls

Installation & compatibility notes

Important: Confirm fit and ratings before ordering. The part number ME36600LS is the best reference for compatibility, so use it to cross-check against your panel model and existing breakers. This ensures a direct, safe replacement without modifying the panel infrastructure.

Practical tips for a smooth swap:

• Verify the panel label and catalog number to ensure a perfect match.
• Keep the replacement in its original packaging until installation to protect the contacts and trip mechanism.
• Follow lockout/tagout procedures and refer to the panel’s wiring diagram during replacement to ensure correct bus connections.
